Briefly explain the governing equation for transient diffusion.
1. [EfTectiveness factor] (a) Consider the following governing equation which can describe the reaction-diffusion inside a porous catalyst with the flat geometry: where C is the concentration of species A, k is the reaction constant, and D is the diffusion coefficient. The corresponding boundary conditions are given by CA = Cas = 1 at x = 0 and = 0 at x = 1 dx The schematic for the domain is illustrated in Fig. I 1-0 CA-CA-1 dC dr Fig....
